Abstract

Process for preparing silicon-containing vinyl ethers and vinyl thioethers of the general formula I ##STR1## where the variables have the following meanings: X is oxygen or sulfur, PA1 R.sup.1 is C.sub.1 -C.sub.20 -alkylene, C.sub.3 -C.sub.12 -cycloalkylene or C.sub.6 -C.sub.10 -arylene, PA1 R.sup.2, R.sup.3 and R.sup.4 are hydrogen, C.sub.1 -C.sub.20 -alkyl, C.sub.3 -C.sub.12 -cycloalkyl, C.sub.1 -C.sub.12 -alkoxy, phenoxy, heteroaryl or together with R.sup.1 form a C.sub.3 -C.sub.12 -cycle, by reaction of silicon-containing alcohols or thiols of the general formula II ##STR2## where the variables have the meaning indicated above, with acetylene, by carrying out the reaction in phenyl methyl sulfoxide, dimethyl sulfoxide, sulfolane or hexamethylphosphoramide in the presence of an alkali metal hydroxide.
